Your code should contain a PHP function that, accepting the string of 1000 numbers in input, is able to:

1) Find the 5 adjacent numbers that multiplied together give the largest product.

2) Given the product from above, computes the sum of the factorial of each term of such product

Example, if the product is 5046, computes 5! + 0! + 4! + 6!

NOTE:

If the file doesn't contain 1000 numbers or contains some characters in between, it should be discarded and the application should inform the user that the file is not format correctly.
Add a tester function to check the behavior of your PHP function.
Follow the guidelines discussed and showed in class to avoid losing points.

Expert Solution

//HTML file

// Prog.php file

<?php

$c = fopen("fname", "r") or die("Can not open File! Try again");
echo fread($c,filesize("input.txt"));
fclose($c);

$inptlen= strlen($c[0]);

if( $inptlen > "999") // checking for the length is 1000 or less that that
{

for($i= 0; $i<$inptlen ; $i++)
{
$asc = ord($c[$i]); // checks whether any character is present or not based on ascii
if ($asc>="48" && $asc<= "57") //as the 0-9 ascii lies from 48-57 , we are checking for that
{
$numb[$i]= (int)$c[$i];
}
else
{
echo "\nWrong !!! file format \n";
}

}
for ($j =0; $j<$inptlen-5;$j++)
{
$mul[$j] = $numb[$j]*$numb[$j+1]*$numb[$j+2]*$numb[$j+3]*$numb[$j+4]; // the multiplication of 5 consecutive values
}
$highest= (string)max($mul); // highest value from the multiplications
$nochar=strlen($highest); // converting number in to digits using string maping
for($k=0;$k<$nochar;$k++) // factorization of digits
{
$fact= 1;
for($g=(int)$highest[$k]; $g>=1; $g--)
{
if($g=="0")
{
$fact=1;
}
else
{
$fact = $fact * $g;
}
}
$factresult[$k]=$fact;
}
$s=0;
for($b=0;$b<$nochar;$b++)
{
$s=$s+$factresult[$b]; //sum of factorials
}
echo "Final Result is :";
echo $s;
}
else
{
echo "Wrong !!! file format \n";
}

?>

Test Function:

Please save the following content in three different text files:

1. please make a text file with the following value using note pad, please remove the word wrap option unchecked and remove the "enters" from the end of the files": The expected output will be of positive output.

2. please make a text file with the following value using note pad, please remove the word wrap option unchecked and remove the "enters" from the end of the files": The expected output will be of negative output for the size of the no of values.
